God, that hurts my eyes.

That's not the correlation, that's just two lines on a chart which shouldn't have lines

What is the time period? Axes labels? Why are you using lines where there's no continuity? God, please rain fire and brimstone on this abomination!

If this was a high school math or data analysis project, this would be graded Zero.

Go back to the drawing board and make a scatter plot with each dot representing one country, but add labels to the axis, and then add the correlation line to it.
